Title: Driving device for motor
Inventor: OKURA KIYOTOSHI
IPC: H02P7/29
Filed: 1993-04-01
Abstract: PURPOSE:To provide a motor driving device in which the controllability of a motor is increased by adding correction to a current command value or a current detection value so that the relation between the current command value and a motor current value becomes linear. CONSTITUTION:Correction is added to a current command value C to obtain a correction command value C'. When a command value output C'', a current detection voltage value C''' and a motor current C'''' are sequentially sought from the correction command value C', finally, a motor current with respect to the command value C makes C''''. Thereby, even when a current detection part has a non-linear element, the relation between the command value C and a motor current C'''' can be made linear to be able to perform precise motor control.

Title: Multiprocessing unit system
Inventor: KAWAI MAKOTO
IPC: G06F15/177
Filed: 1982-06-12
Abstract: PURPOSE:To minimize the addition of hardware and to set and change DMA priority easily by providing a shared memory with a DMA priority easily by providing a shared memory with a DMA priority setting area, and setting and changing the DMA priority. CONSTITUTION:When a CPU-P1 is given the right to access, the signal -BGATE of the CPU-P1 turns on, so gates 15-17 are opened and a signal ACK also turns on, so that DMA access stand-by mode is reset. A microprocessor 9 sends out address data for specifying the priority setting area to an address bus Ba through a gate 14 and set the CPU-P1 top priority regarding a data bus Bd through the gate 15. The CPU-P1 decodes the address data by a decoder 1 to perform DMA access operation. If, however, the DMA access request signal -DMRQ is not sent out at this point of time, an OR gate 8 outputs ''0'' and the right to access is passed to another CPU.

Title: Synchronous signal detection matching circuit
Inventor: AKIBA KUNIO
IPC: H04L7/00
Filed: 1978-08-18
Abstract: PURPOSE:To realize an AM synchronous signal detection matching which is highly resistant to the noise and suited for the synchronous matching even for the radio circuit of a low S/N ratio in case the data is transmitted by radio. CONSTITUTION:Only the subcarrier signal component of the input signal passes through BPF1 and is then reduced down to a fixed level via AGC circuit 2 to be supplied to weighting circuit 3 in the form of signal (a) along with signal (b). Thus weighting addition signal (c) is delivered. Signal (c) is then delayed for a fixed time through delay circuit 4 and supplied to circuit 3 in the form of signal (b). Here the constant is decided properly for the signal supplied once to decide the residue rate. The delay time of circuit 4 is set to an integer-fold value identical to the cycle of the synchronous signal. In case the noise exists in the communication line, the noise phase is random to the phase of the subcarrier but averaged through repetition of addition. And only the signal component is emphasized. The output of circuit 3 is applied to rectifier circuit 5 and slicing circuit 6 to detect the synchronous signal. Furthermore, a high resistance is obtained even to the impulsive noise by deciding the constant properly.

Title: Heat resistant optical fiber
Inventor: HASHIBA KEIICHI
IPC: G02B6/44
Filed: 1991-05-07
Abstract: PURPOSE:To allow the stable use of the above fiber even in a high-temp. region by providing a hydrogen preventive layer on the clad of the optical fiber. CONSTITUTION:A coating material 4 which is polyimide is partly decomposed and a slight amt. of gaseous hydrogen is generated when the heat resistant optical fiber 1 is placed in an atmosphere kept at, for example, >=400 deg.C. Since the optical fiber 2 is housed in a metallic tube 3, this gaseous hydrogen fills the inside of the metallic tube 3 and diffuses into the optical fiber 2. The hydrogen preventive layer 7 contains GeO2, and P2O5, sensitive with the hydrogen at high ratios and, therefore, if the hydrogen arrives at the hydrogen preventive layer 7, the hydrogen combines with the structural defect of the glass of the hydrogen preventive layer 7 and is trapped therein. The diffusion of the hydrogen harmful to the optical fiber 2 is blocked by the hydrogen preventive layer 7 in such a manner, by which the diffusion of the hydrogen into a core 5 is substantially obviated and, therefore, an increase of a light loss is prevented. The deterioration in the initial loss characteristic is prevented if the plural hydrogen preventive layers are so disposed that the structural defects of the glass decrease the nearer the core.
